Change to use the print wrappers instead of fprintf().

This is example output of the options part before this commit:

        "options": {
            "handle": 1,
            "in_hw": true,
            "actions": [ {
                    "order": 1 police 0x2 ,
                    "control_action": {
                        "type": "drop"
                    },
                    "control_action": {
                        "type": "continue"
                    }overhead 0b linklayer unspec
        ref 1 bind 1
,
                    "used_hw_stats": [ "delayed" ]
                } ]
        }

This is the output of the same dump with this commit:

        "options": {
            "handle": 1,
            "in_hw": true,
            "actions": [ {
                    "order": 1,
                    "kind": "police",
                    "index": 2,
                    "control_action": {
                        "type": "drop"
                    },
                    "control_action": {
                        "type": "continue"
                    },
                    "overhead": 0,
                    "linklayer": "unspec",
                    "ref": 1,
                    "bind": 1,
                    "used_hw_stats": [ "delayed" ]
                } ]
        }

Notes:
    v2
    - fix json output to match correctly the other actions
      i.e. output the action name in key 'kind' and unsigned for the index
    
    v3
    - print errors to stderr.
    - return -1 on null key.

why '|| true'? leftover from special casing tests?
